(54) Two-switch device for an electric nail gun


(57) A two-switch device is used for an electric nail gun. The electric nail gun includes a safety member (12) movable to press against an article (A) to thereby move in the gun body (11), a kinetic power unit (13) for generating kinetic energy, an impact unit (14) for outputting kinetic energy to perform a nail-striking operation, and a transmission unit (15) for transmitting the kinetic energy. The two-switch device includes a trigger unit (2), a first electrical control unit (3) controlled by a trigger (21) of the trigger unit (2) and the safety member (12) for driving the kinetic power unit (13), and a second electrical control unit (4) controlled by an inner plate (22) of the trigger unit (2) for driving the transmission unit (15). By controlling actuation order of the safety member (12) and the trigger (21), the electric nail gun can be changed between a single shot mode and a continuous shooting mode.
